I cleared the cache and history. The page displayed correctly, however my customization was gone. I replaced the custom.css with mine (because I upgraded the theme the old one was being used) and now the problem reappears. It must be something in my custom.css file that causes it. I tried removing the “.form-row{clear:right;}” element, but no change. I don’t know what else it could be. Would you have any idea where this could be happening.

I remember having this issue in the past and now I found the following thread: http://www.kriesi.at/support/topic/checkout-page-not-displaying-properly where a temporary solution was provided, which I implemented, and that was supposed to be fixed in the following upgrade of the theme. Also, I clicked on one of the website link that that thread and tested the checkout page. It has the same issue and me.

Not really sure what to tell you. Your custom.css file causes the problem and the default theme files do not. If this is the case, you’ll need to go through the custom css, add in each rule individually until you can find the culprit.
